When did any of you get the idea the guy was wearing a dress? He's a strongman by profession, he wears a strongman outfit-

Kind of like a one-piece bathing suit? He's got to show off his manly manly muscles but preserve modesty in a way he would not have to had he been a modern bodybuilder.

EDIT: And even if he was wearing a dress, that doesn't by default make him less manly- Ancient Romans, who wore togas more or less exclusively, thought the pants the germanic barbarians wore were effeminate. Clothing acquires manliness by virtue of being worn by manly people- Checkered red logger shirts are manly because they are worn by manly lumberjacks, strongman outfits by strongmen, suits of shining armor by knights, kilts by Celts, etc.
